Description

Technical Field

[0001] The utility model relates to the technical field of metal recovery equipment, and more specifically, to a metal recovery equipment in domestic incineration garbage. Background Art

[0002] Incineration of municipal solid waste is a treatment method that converts waste into ash and waste gas through high-temperature oxidation. Incineration technology can effectively reduce the volume and weight of waste, reduce the demand for landfills, and also generate energy or heat. However, during the incineration process, the metal part of the waste usually cannot be burned and remains in the ash.

[0003] These metals can be recycled and reused to reduce the consumption of natural resources and contribute to the circular economy. Metals include magnetic iron and non-magnetic copper and aluminum. The existing technology often uses a combination of magnetic separation and eddy current separation. Magnetic separation uses the principle of magnetic adsorption, and eddy current separation uses the high-speed rotation of the magnet drum to generate an alternating magnetic field. When the conductive metal passes through the magnetic field, eddy currents will be generated in the metal. The eddy current itself generates an alternating magnetic field, which is opposite to the direction of the magnetic field generated by the magnet drum, that is, it generates a repulsive force (Lorentz force) on the metal, causing the metal to jump out and achieve the purpose of separation.

[0004] In practical applications, an upper and lower conveyor belt is required. The lower conveyor belt transports the original ash, and the upper conveyor belt is located vertically above it. A magnetic suction mechanism is provided at one end of its inner side. The iron is first sucked upward by magnetic suction. As the upper conveyor belt moves to the other end, this part of the iron falls from the conveyor belt and is collected due to the loss of magnetic suction, while the ash with the iron removed continues to move along the lower conveyor belt to the eddy current sorting area for further sorting.

[0005] However, due to the irregularity of metal fragments, some ash will be picked up when they are sucked up, and the upper conveyor belt is open. During the shaking process of the upper conveyor belt, the ash will fall off and fly in the air, causing a poor workshop environment. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a metal recovery equipment from domestic incineration waste, by which the first diversion channel or the second diversion channel is opened alternately through the arranged diversion plate. When the ash is discharged into the first diversion channel to separate the iron block, the air duct in the second diversion channel blows toward the electromagnet adsorption area, thereby blowing off the ash carried on the iron block, and then discharging it from the discharge port. The iron removal process is carried out in a relatively closed environment, thereby avoiding the flying of ash and improving the environmental quality of the workshop.
